1. Is your PC/laptop noisy or overheating? Get it internally cleaned and have the thermal paste replaced!
2. Is your PC/laptop slow? Replace your current storage device with an SSD or nVme!
3. ALWAYS keep your important data on cloud! I recommend MEGA.nz for 2 reasons: I) it's end-to-end encrypted & II) it's cheaper per TB of data than Dropbox and GoogleDrive
